Methods of applying a polymer coating to a substrate are disclosed. By disrupting a bank (8) of polymer precursor, a smooth coating of fast setting polymer can be applied to a substrate. Apparatus (5) for applying a polymer coating is also disclosed. In one embodiment, an oscillating dispenser is used to apply polymer precursor onto a dispersive surface (30). The polymer precursor flows down the surface (30) and is transferred to a moving web (50). Flowing solvent downwardly through the dispenser can provide efficient cleaning without the need for disassembly or production delays.
